difference between uPVC and PVCu

What is the difference between uPVC and PVCu?

If you’ve seen the phrases uPVC and PVCu used to describe windows and doors, you might be confused. Is there a distinction between the two? What is the difference between uPVC and PVCu? Consumers today are frequently perplexed about which sort of doors and windows to buy for their homes, but with enough information, they can make an informed decision. So keep reading to learn more about the meanings of these phrases and the benefits that these types of windows and doors can provide for your home.

difference between uPVC and PVCu

What is uPVC?

Polyvinyl Chloride is a common, strong, and lightweight plastic used as a building material. The “u” stands for “un-plasticised,” which means the plastic isn’t softened during production and retains its strength. Because of its many advantages, such as resistance to chemicals, sunlight, and oxidation from water, it has grown in popularity in the home improvement industry and has become an alternative to painted timber. It is low-cost and low-maintenance, which makes it especially suitable for double-glazed windows and doors. Roofline products such as downpipes, guttering, and fascias can also be made of uPVC.

What’s the difference between UPVC & PVCu?

As we are sure you can tell by now, there is no difference between UPVC and PVCu because they both refer to the same material, Un-plasticised Poly Vinyl Chloride. UPVC is used by installers to promote windows, doors, and other home improvement products, but it is also known as PVCu. Because most languages pronounce the PVC before the U, the change was made in the 1980s to align with European standards in order to create a universal naming convention.

Why do we use uPVC for windows and doors?

PVCu (or uPVC, depending on your preference) is the most commonly used material in the UK today. It is used to manufacture the casement and frames of home improvement products such as doors and windows. Because of its strong composition and lightweight design, which can withstand even the most extreme weather conditions, it is a popular alternative to standard PVC and wood. It is also a very affordable option for consumers.

What are the benefits of using uPVC?

At Supercraft Windows, we have a fantastic selection of uPVC windows, as well as entrance doors, french doors, and patio doors. PVCu is the most common material used to make the frames and casements of windows, doors, and other home improvement products, and it’s probably one of the most popular alternatives to wood and PVC. PVCu is lightweight and has a strong composition, which allows it to withstand the harshest weather conditions while lowering consumer costs.

The benefits of PVCu are:

  • It is resilient and does not discolour in extreme sunlight
  • PVCu can withstand extreme weather conditions
  • It has a lightweight design
  • it retains its shape during normal temperatures
  • It is strong which means it can endure heavy impacts
  • It ages well

How to secure your windows at home

How To Secure Your Windows at Home

It’s essential to feel protected in your house, but break-ins can happen at any time. If you want to improve home security, your windows, as one of the most vulnerable areas in your home, require special attention. With these suggestions, you’ll be able to relax and enjoy the peace of mind that comes with a safer house. Here’s how to secure your windows at home.


When a burglar comes across a locked window, the first thing they do is try to break it open. Installing impact-resistant security glass is significantly more difficult to break than regular windows and can help deter burglars. Two or more layers of polyvinyl butyral laminating material are employed to fuse the panes together (PVB). This makes your windows extremely resistant to breakage attempts. Security glass may also protect you from harsh weather.


Many burglars gain access to a home by simply accessing an unlocked window or door. Make it a habit to lock your windows and doors every time you close them to make these openings more secure. If the original window locks appear to be fragile, try installing additional locks to feel more secure.


The multi-point locking system of the GripLock Casement lock ensures maximum security. In addition, for ultimate safety and security, we employ a Fab&Fix Handle, a Yale 6 Pin Cylinder lock, Yale Hinge Guards, and the Yale Friction Stay system as standard. This lock has been force tested and found to withstand over 4700 Newtons of force, making it the UK’s strongest and most secure lock.


Burglars will not be able to fit through your windows and get inside your home if you have bars on them. Burglar bars come in various colours and styles which helps to make your home look less like a jail. Consider installing the bars only on ground-floor windows so that people in the home can escape through second-story windows if necessary.


A security screen is similar to an insect screen in that it keeps bugs out, but the mesh of a security screen is composed of steel, making it much harder and more difficult to cut with a knife. According to research, if breaking into a building takes more than four or five minutes, the burglar will abandon the attempt rather than risk getting detected.


We take home security very seriously at Supercraft Windows. That is why we offer security glass windows. Please visit our local store in Stoke-on-Trent if you’re interested in installing these security upgrades in your house. We’ll answer any remaining questions you have regarding window security features and suggest solutions that will be most beneficial to you.

Replace Your Windows During Spring

Why You Should Replace Your Windows During Spring

There are several good reasons why spring is such a popular season for home remodelling. Sunny spring days have a way of energizing us and creating a sense of productivity. It is a terrific time to get things done around the house—from spring cleaning the junk collected over the previous months to revitalizing our décor. So, open the windows, get some fresh air, and start the spring cleaning project—and pay attention to those old-fashioned and broken windows. But is it time for replacement windows?

Replacing windows is a big investment, but if you notice any of these signs, then it might be time for an upgrade. Drafty windows can be a pain, and the cost of a window replacement seems reasonable compared to lofty energy bills during the summer months. Another thing to consider is the window frames. No amount of repairs will help if frames are soft or cracked, and even worse, warped. Additionally, summer means more outdoor activities, so you might notice that your old windows aren’t as soundproof as they once were. Lastly, condensation can be the main sign of poor energy efficiency, which means you’ll have to run your cooling system more to keep your home comfortable during summer.

So, why should you replace your windows during spring?

Get a fresh, new look this spring

New windows are an excellent way to finish your spring cleaning with a lovely style improvement. New windows during spring mean your home will look stunning inside and out, providing natural lighting and great curb appeal. From bay windows to casement windows, spring has so much in store for your home.

Air out your home

During the winter, our windows aren’t open very much. And now that spring has arrived, everyone wants to let some fresh air in. However, opening the windows might be tough if they’ve been shut for a while and are otherwise difficult to operate. New windows allow you to air out your home after a long, damp, and musty winter. From awning windows that let in a soft breeze during spring showers to casement windows that provide easy ventilation above the kitchen sink, we’ve got what you need this spring.

Save on energy bills this summer

If your windows are old and drafty, you may have had to pay exorbitant energy bills this winter. During the summer, don’t continue to waste money on ineffective windows. Using double and triple-glazed glass, and UV-resistant coatings, you can enjoy plenty of energy-saving features when you opt for modern replacement windows.

Easy installation during the spring months

In the spring, there are additional daylight hours, allowing you to finish your project sooner. Because of the cooler temperatures and lower humidity, window installation is also more pleasant in the spring. Getting new windows in the spring is therefore a no-brainer—for both you and window contractors.

Benefits of Casement Windows

Ever wonder what a casement window is? Are you looking for a window replacement that is easy to open and close? Then a casement window might be the right choice for you. 

Casement windows are a perfect choice if you’re looking to achieve noise minimisation and reduced heat loss. They are a popular option for contemporary homes. These modern windows give you everything—from stunning design and durability to security and more access to the outdoors. But what is a casement window and what are the benefits?

What are Casement Windows?

A casement window opens outward to the left or right and hinges on the side. They’re also known as crank windows since they’re opened by cranking the window’s supporting arm outward with a handle. Our casement windows have an easy-turn, fold-down handle that makes opening and closing a breeze.

Here are some of the benefits of casement windows.

More airflow

Casement windows are designed to open all the way depending on your needs. You can capture more air if you can totally open your windows. So casement windows also allow for a greater amount of circulation to pass through your home. Casement windows would ideally suit your demands if you prefer to ventilate your home with natural air whenever available. They let in fresh air while keeping undesirable particles and insects out when used with screens.

Energy efficient

Casement windows are distinguished by their tight seals on all four sides, which can also be strengthened by severe winds. Rail windows allow more air to escape, whereas casement windows prevent air from escaping through tiny holes along the edges of the frames. For homeowners, saving money is always a priority. Casement windows can be closed tightly by hand, sealing the window and preventing energy leakage. Consider casement windows if you want to save money on your utility expenses. 

Versatile design

Every home is unique, and each family has slightly different needs. To match the casement windows to your home and personal taste, you can choose from a variety of handle designs, glass, hinges, and colours. Casement windows also have the extra benefit of looking good with other types of windows. So, this allows you to combine casement windows with double-hung windows, picture windows, and windows of odd shapes. In general, you’ll want to pick a space with plenty of natural light and unrestricted access to the outdoors.

Minimal Maintenance

Supercraft casement windows are made to last and will not decay like wooden frames. Simply grease the hinges on a regular basis to keep the system in top shape.

Why are Supercraft Casement Windows the Best Option?

The surface area of a casement window functions as a sail, catching the wind and bringing it into your home, allowing for optimal ventilation in your space. Casement windows come in a variety of styles and sizes, allowing you to design the perfect window for your home. Our professionals are with you every step of the way, from the initial in-home estimate to the installation of your windows.

aluminium windows and doors

Advantages of Aluminium Windows and Doors

Aluminium windows and doors are quickly becoming one of the most popular materials installed in both homes and commercial buildings across the UK, thanks to their perfect balance of design and performance. What are the advantages of aluminium windows and doors, though? And, how does aluminium compare to other materials like uPVC, wood, and steel?

Although different options will suit different individuals or projects, and there is no perfect answer as to which material is the “best,” this post will focus on the advantages of aluminium. So, here are five reasons why we believe aluminium windows and doors might be better.


Aluminium simply looks attractive to a lot of people. Owners of both homes and businesses will have preferences about which products seem better. Some people prefer the uPVC look, while others prefer the natural beauty of wood—but many people agree that aluminium windows and doors are a great option for a trendy and modern appeal. Aluminium requires less frame to support the weight of the glass because of its strength, allowing for greater glass surfaces. This is very advantageous and appealing in modern constructions, especially when compared to uPVC, which requires a larger frame.

Durability and strength

Aluminium windows and doors are incredibly sturdy and lasting, providing numerous advantages. Aluminium is a non-rusting and corrosion-resistant material, making it ideal for enduring the elements – whether it’s the corrosive British rain or the ferocious winds of the seashore. Although modern steel window and door systems will have rust protection, there is no such risk with aluminium, and because of its sturdy structure, aluminium is preferred over conventional wood products in high-wind regions.

Furthermore, the strength of aluminium windows and doors ensures a longer product life and increased security for your house or business.

Easy to maintain

Aluminium windows and doors require very minimal maintenance if installed and manufactured by professionals. These products are corrosion and weather-resistant, as well as easy to maintain—the elegant framework only requires a clean wipe every now and again. When compared to other materials, such as wood, aluminium requires significantly less upkeep.


Timber and steel products are both more expensive than aluminium, with steel being pricier. Different products may be appropriate for different projects, but aluminium is a low-cost material that does not require compromises in terms of strength, durability, or style. Aluminium is more expensive when compared to uPVC. However, because of the material’s long product life and the low maintenance required by the doors and windows, aluminium may be considered less expensive in the long run.

Environmentally friendly

Aluminium is a sustainable material that is 100 per cent recyclable, making it far more eco-friendly than uPVC and aiding in the reduction of timber loss. Aluminium windows and doors are also advantageous in that they can keep heat inside your homes, businesses, and structures, reducing the need for heating. Once again, this is a personal preference, but one advantage of aluminium is its ability to maintain a low carbon footprint.

Prevent Window Condensation

Measures to Prevent Window Condensation

Condensation on windows can be bothersome. While window condensation is a good indicator of excessive humidity levels, these measures can help you prevent window condensation.

Condensation on windows can be aggravating. Recurring condensation can cause long-term window damage if left ignored. With these tips, you can keep your windows in good working order and reduce internal and external condensation.

Tips for Reducing Window Condensation Inside and Outside

Peering through cloudy windowpanes caused by interior or exterior window moisture is not pleasant. When the temperature of the air outside and the temperature of the glass are significantly different, window condensation is common. While both interior and exterior window condensation can be annoying, untreated internal moisture is more likely to cause long-term issues. Condensation on the inside and outside of windows is not a symptom of a faulty window, and there are several ways to eliminate condensation in your home.

Condensation on the Inside of Windows

Condensation forms first on windows because glass surfaces are frequently among the coldest elements of your home. This usually manifests itself as water droplets or ice on the inside of your window. Condensation begins to dissipate as the internal air becomes dryer or the glass surface grows warmer.

What causes interior window condensation?

When warm air comes into contact with cool glass on the inside of windows and doors, condensation forms. This is especially prevalent during the winter when the inside air is warmer and more humid and outdoor air is cold and dry. Even if you don’t have a humidifier running, regular activities like bathing, cooking, and even breathing add to the humidity in your home.

Replacement of drafty windows and doors, as well as the installation of a new roof or siding, lowers air infiltration and creates a tighter seal in your home. Although a tighter seal saves money on energy bills, it also retains more humidity, which means condensation on colder surfaces in the home may occur more frequently as a result of these improvements. Mold and mildew thrive in wet settings and organic materials like wood, consequently, indoor window condensation can lead to their growth. Consider condensation on your windows as a warning sign that it’s time to lower the humidity in your home before worse problems arise.

How can I reduce window condensation inside my home?

You can reduce the amount of humidity in your home in a variety of ways. Using a portable dehumidifier or installing a whole-home dehumidifier are two options for reducing air moisture. Cover pots and pans when cooking to keep extra humidity at bay, and make sure the kitchen exhaust fan is turned on. The same can be said for restroom fans. Leaving the bathroom fan on during and after a shower will assist in the removal of humid air from your home. Finally, leaving inside doors open allows for optimum air circulation, preventing humidity from building up in one area.

Condensation on the Outside of Windows

Exterior condensation is more common during the summer months when the outside humidity is higher. When the temperature of the glass is reduced and it comes into touch with that warm, humid air, exterior window condensation happens in the same way as room-side condensation. Condensation on the outside of windows is not a cause for concern. In fact, it’s usually a good sign of a well-functioning window.

What causes condensation on the outside of my windows?

When your window glass is colder than the dew point outside, condensation, or dew, is likely to form on the outside of your window. When the air becomes entirely saturated with water, dew forms spontaneously. High external humidity, little or no breeze, and a bright night sky are the three main causes of exterior window condensation. After a chilly night, homeowners are more likely to see exterior window condensation early in the morning. The dew on the outside of your windows will evaporate as the sun shines and warms the glass.

How can I reduce exterior condensation?

Open window coverings at night to warm up the external glass to prevent exterior condensation. You can also help enhance air circulation by trimming shrubs near windows or doors. Raising the temperature setting on your air conditioner may also help keep your window glass at a warmer temperature.

If you think it might be time to replace or upgrade the windows in your home, contact your local Supercraft installer to schedule a no-obligation consultation to discuss the solutions that might be right for you.

Benefits of Energy Efficient Windows and Doors

The Benefits of Energy Efficient Windows and Doors in Your Home

You will inevitably find your way home, whether you are on holiday or at work. Because we spend the majority of our time at home, many people consider their homes to be important assets. Windows and doors are among the most important structural aspects of any home, and it’s necessary to make sure they are energy-efficient. We gathered a few benefits of energy-efficient windows and doors.

Better insulation for your home

Energy-efficient doors and windows are important for reducing cold and hot zones in your home because they provide a barrier that keeps summer heat and winter cold out. You won’t have to avoid those certain areas in your house that seem 10 degrees hotter in the summer and 10 degrees colder in the winter thanks to energy-efficient doors and windows.

It’s the eco-friendly option

Windows and doors that are energy efficient are better for the environment. Many people are taking steps to reduce their carbon footprint in their homes as awareness of the implications of global warming and climate change grows. Installing energy-efficient windows and doors is one of the most effective ways to decrease your home’s carbon footprint. Some homeowners are unaware of how much energy is lost through their doors and windows. Because of its high thermal reflection capabilities, energy-efficient doors and windows help to control temperatures in your home, requiring less fossil fuel-powered electricity to maintain the correct temperature and making your home more environmentally friendly.


The superb soundproofing of energy-efficient windows and doors is one of their most remarkable features. External factors, such as noise, are effectively blocked by these structural components. This is a significant benefit, particularly in neighbourhoods where houses are situated close together or near train tracks or major roadways.

They reduce maintenance

By reducing energy transfer, energy-efficient doors and windows help to decrease condensation buildup. This is especially essential for persons with asthma and other allergies since it decreases mold exposure. Furthermore, because of their UV-resistant coating, eco-friendly windows and doors frequently have little to no dirt and water buildup. This means that window cleaning and dusting are the only things that need to be done.

They increase your property value

Energy efficiency is one of the issues that homebuyers assess when making a purchase.

3 Window Privacy Ideas For Your Home

When you’re looking for just the right mix of both natural light and privacy at home, these window privacy ideas might help. 

Maximizing natural light through a large number of windows and doors is extremely appealing, as it brightens areas and improves emotions. However, there are some areas of the house that require a little more seclusion. Bathrooms are one of them, but so are other areas such as a home office or a bedroom. Even a public meeting spot in the home, such as a sitting room, can benefit from privacy on occasion. So, if you want to take advantage of natural light while also wanting some privacy, here are 3 window privacy ideas for your home.


window privacy ideas

Skylights can provide the same level of seclusion as awning windows positioned high up. A strategically placed skylight lets in natural light while maintaining privacy. If you’re thinking about adding skylights, think about the type you want. Is it possible to have the function you want with a fixed, non-venting skylight, or does ventilation play a role in your decision? In either case, a skylight in your home will provide natural light and seclusion while maintaining security.

Curtains or Blinds 

window privacy ideas

Installing drapes or blinds may be the first privacy solution that comes to mind for most people. When changing windows and starting on a full renovation project is not an option, this is certainly one approach to reduce exposure to the outside. It can also be a simple, elegant, and cost-effective solution. Homeowners can obtain a more modern look by incorporating translucent materials into their blinds (and as a bonus, they can avoid the dust that collects in Venetian-style blinds).

Tinted or Decorative Glass 

With tinted, decorative, or textured glass, you can achieve privacy while also adding a touch of style. A bronze, grey, or green hue can create a peaceful and secluded atmosphere in your home, as well as a honeyed hue on the outside. And decorative glass can have a watery translucent appearance, or an opaque sequin appearance, which could provide the solitude you seek while also adding charm. When choosing tinted or decorative glass as a privacy solution, look through the possibilities because there are so many to choose from that you can truly create a bespoke, one-of-a-kind place.

Triple Glazed Windows: What Are The Benefits?

Triple glazed windows are becoming a popular option for today’s homeowners and suppliers, but long-standing concerns about the costs overshadowing the real benefits are on many homeowner’s minds. As experts in the Windows and Doors industry, Supercraft Windows is here to help you understand more about triple glazing and its benefits.

So, what is triple glazing?

Triple glazing is a window that has three panes of glass sealed within a frame. The glass is separated by small gaps filled with argon gas, which is heavier than air, making it more difficult for heat to escape—providing efficient insulation against cold and noise pollution.

While double glazing is a worthwhile addition to any home, triple glazing goes beyond a certain level. However, it sits at a higher price range than double glazing, so you might be wondering whether it’s worth spending more money on triple glazing rather than double glazing.

What makes triple glazing energy efficient?

A big selling point for triple glazing is the energy efficiency it provides. The air gaps in triple glazed windows are filled with argon gas which is a poor conductor and reduces heat loss through the window. The gaps are too small to circulate air, and the argon gas improves thermal efficiency because it stops heat from escaping. Furthermore, the additional pane is said to reduce the levels of noise from outside.

Triple glazed windows reduce outside noise.

A further advantage of triple glazing is that it reduces the noise from outside. Homeowners who live in a noisy neighbourhood might be inclined to choose triple glazing over double glazing for this fact. So why do triple glazed windows reduce sound? Simply put, the extra glass pane makes it harder for outside sounds to reach inside.

Is triple glazing more secure?

Not only does triple glazing help with thermal efficiency and reduce energy costs, but it also makes your home more secure. The extra pane of thick glass makes a window tougher to break, discouraging any potential intruder and acting as a deterrent. Combine triple glazing with our Yale GripLock system, and you can rest assured that your home is safe and secure—giving you the ultimate peace of mind.

The Yale GripLock system is included as standard in all UPVC Windows and Doors from Supercraft.

6 Signs You Need New Windows and Doors

6 Signs You Need New Windows and Doors

Timing is an essential part of planning a window and door replacement. Failing windows and doors can often make your favourite places less comfortable, but they can also decrease your quality of life and may have a negative impact on your health. It is important to spot the telltale signs of window and door failure, and here are a few tips on how to tell when it’s time for a replacement.

As time goes on, the performance of your windows and doors will diminish—from damaged weather stripping and failing seals to brittle components and cracked glass. There are some obvious signs, like higher energy bills, drafty rooms, or windows and doors becoming hard to open and close. So, here are a few things to keep an eye out for.

Higher Energy Bills

When windows and doors are underperforming, it only makes sense that your energy bills will be higher. As your old, single-pane windows reach the end of their cycle, leaks and fine cracks start to form, and once the air-tight seal is damaged, the only way to eliminate drafts in your house is to replace the windows. The small cracks and holes between the panes allow cold air to enter, and this causes your energy bills to increase each month, especially during the winter months as you try to stay warm.

Excessive Window Condensation Between the Glass Panes

Windows are among the most prevalent spots in your house for condensation to occur because window panes are generally the coldest surface. Due to direct contact with the outside cold in autumn or winter, the inner surface of the glass pane is usually as cold as the outside air. Glass panels are the most prone to condensation, but you can also find moisture on window frames and fixtures. Condensation can mean that the current glazing on the windows is losing its effectiveness, and if the seals are failing, it’s easy for moisture to find its way between the glass panels, which forms condensation. When that condensation dries, it can leave behind an irritating foggy film that can’t be clean, and it can negatively affect a window’s performance.

Musty Smells

If your windows have been installed poorly, they can lose their ability to prevent water from coming into your home. And, of course, where there is water, there is often mould. Mould can be a real health concern and often can’t be seen if it’s growing in your walls so, the only sign might be a musty smell. Using specialised tools like infrared cameras, a window and door expert can evaluate the situation in your house and let you know whether your windows and doors are causing a problem.

Water Damage on Window Frames

When the paint starts chipping off on window frames, it’s easy to give them a fresh coat of paint. However, if the frames are no longer holding the coat of paint, it might be time for an upgrade. When water finds its way past gaskets and seals and into the painted areas, it causes the paint to fail from the inside out.

They’re Old

If your windows and doors, and even the trim around them, were installed decades ago, it is probably a good idea to replace them. Old windows and doors can cause many problems. Old windows usually have single panes, which can cause a room to be too cold in the winter and too warm in the summer and can make your home quite uncomfortable.

Noise From Outside

Do you hear every car horn, dog barking, and other traffic noise in your home? If you want to know when is the best time to replace windows, too much noise indicates that your windows do not provide enough insulation. Double or triple glazed windows are not only warmer, but they prevent up to 90% of outside noise from entering your home.
